7-Iodo-1,2,3,4-tetrahydropyrido[2,3-b]pyrazine (300 mg) was dissolved in anhydrous pyridine. Phenylsulfonyl chloride (1.0 eq) was added and the reaction mixture was heated to 100° C. in a microwave oven for 10 minutes. Silica gel chromatography gave the title compound as a pale orange solid (23% yield). M.p. 145-146° C., LCMS: m/z=407.71 (M+H+), 1H-NMR (CDCl3, 400 MHz) δ 2.94-2.99 (m, 2H), 3.74 (t, J=5.0 Hz, 2H), 4.83 (bs, 1H), 7.45-7.49 (m, 2H), 7.58-7.65 (m, 3H), 8.06 (d, J=2.0 Hz, 1H), 8.17 (d, J=2.0 Hz, 1H).
